Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank. From this tank it

1/1/2011 · In this example, as water leaked out via a loose rolled-in tube joint at a boiler drum, it flashed to steam. At that point, dissolved caustic alkalinity in the boiler water can concentrate sufficient caustic via evaporative concentration to produce branched, predominately intergranular stress corrosion cracking in the steel microstructure (see Fig. 14.3 ).

The pipework between the boiler and the steam accumulator should be sized, as per normal practice, on a steam velocity of 25 to 30 m/s and the maximum output of the boiler. In the case of Example 3.22.2, this would require a DN100 pipeline from the boiler to the accumulator, to carry the boiler Maximum Continuous Rating (MCR) of 5 000 kg/h @ 10 bar g.

Boiler water treatment is done to minimize corrosion, deposition, scale, and carryover in the water–steam circuits. The aim is to maximize the reliability of the steam–water circuit. Boiler water treatment has basically two phases: First, we remove impurities from the water to the desired cleanliness.

The purpose of a steam accumulator is to release steam when the demand is greater than the boiler's ability to supply at that time, and to accept steam when demand is low. Find about about the need for steam storage to meet peak load demands in specific industries, including the design, construction and operation of a steam accumulator, with calculations.
